    摘要: A method for forming inserts for steam cooled hot gas path components involves casting the inserts (10) and laser drilling (14) the cast inserts (10) with the ceramic casting core (12) still in place. Thereafter, the ceramic core (12) is removed through the use of a leachant. By laser drilling (14) the holes (16) with the ceramic core (12) still in place, the ceramic core (12) acts as a backer during the laser drilling (14) which results in more precise drilling of the inserts (10) and reduced processing time.

    摘要: A thermal barrier coating (TBC) system (110) is provided. The system includes at least one thermal barrier coating (TBC) bond coat layer (112) formed over a substrate surface region (108). The TBC bond coat layer includes at least one TBC bond coat material. The TBC bond coat material is a nickel-chromium-aluminum-yttrium (NiCrAIY) composition that also includes silicon (Si), hafnium (Hf) and less than 10 weight percent (wt%) cobalt (Co). The TBC system further includes at least one top coat layer (120) formed over the TBC bond coat layer.

    摘要: A thermal barrier coating system for use on metal alloy components exposed to hostile thermal and chemical environment, such as a gas turbine engine used to generate electricity comprises a thermal barrier layer formed using a dense vertical cracking process and consists of zirconia that is partially stabilized by 1 to 6 weight percent yttria, preferably less than 4 weight percent yttria and 0-1 weight percent hafnia. The ceramic layer is optimized to protect the underlying superalloy component from erosion, chipping, and handling, while reducing the cost of the protective layer. An alternative method of preparing the thermal barrier coating uses electron beam physical vapor deposition.
